$BNB BNB (Binance Coin) is the native cryptocurrency of the Binance exchange, originally launched as an ERC-20 token before migrating to Binance's own blockchain, Binance Chain. Initially, it was created to offer discounted fees for users of the Binance platform, but over time, BNB has grown in utility and value. Today, it serves multiple functions, including transaction fees, staking, participation in token sales, and as a method of payment within the Binance ecosystem. BNB also plays a key role in the Binance Smart Chain (BSC), enabling faster, low-cost transactions and supporting decentralized finance (DeFi) applications. As Binance continues to innovate and expand, BNB's use cases continue to evolve, making it a central asset in the crypto world.
